I have run both. The 3 inch seemed to make my exhaust louder, but I really couldnt tell driving. I would just get the 3 inch for piece of mind. I like knowing im getting every last hp i can. Your going to hit the dyno and its going to be 399 instead of 400hp lol Just get the 3.

HP is like a seductive temptress, we're never really fully satisfied because she won't let us be. $100 for Racelands it tempting, but you know it will be a tease and you'll be left wondering "what if I just spent the extra money for the 3"...until you eventually give in and buy them.

See, I just saved you a hundred dollars and the install/uninstall/install time.

It's one thing if they're cheap and they fit, but when I bought Raceland's, they didn't fit and I had the worst time trying to get them to work. I spend around 10 hours wrestling with those pieces of $#@!, and another 2-4 hours adjusting them over and over trying to get them to fit without leaking. I then got some AR 3" downpipes and slapped them in without any issues in about an hour. Time is money, and if I were to do it all over again, I'd pick up the AR's again without question. They actually fit, and the quality is about a million times better. But that's just my opinion....

Exactly, you already learned the lesson that you get what you pay for.
